Theorem 2.2 [1]}
Let \(f\in \mathcal {F}_{\mu ,L}(\mathbb {R}^n)\) . If \(t_k=\tfrac{1}{\ell _{\max }}\)  for each \(k\) , and \(\mu >0\) , then, for all \(N>0\) ,
\(\operatorname{\mathbb {E}}\left[f(x^{N}) \right]-f^\star \le \left(1-\tfrac{\mu }{n\ell _{\max }}\right)^N \left(f(x^{0})-f^\star \right) .\)
